KARL FR. HUMMEL, OF GOTTLIEBEN, SWITZERLAND.

VENEERING-PRESS.

To all whom it may concern:

Be it known that I, KARL FR. HUMMEL, a citizen of Switzerland, and resident of Gottlieben, Thurgau, Switzerland, have invented certain new and usei ul Improvements in and Relating to Veneering-Presses, of which the following is a specification.

The object oiI my present invention relates to a veneering press in which one oi' the press plates e. g. the upper one is pressed by means oi' a regulator spindle against a number oi' springs the action or" which can be partly disengaged.

In the accompanyingl drawing in which I have illustrated my invention like letters oi reference refer to like parts of the different views.

In said drawings z-Figure l shows a side view of the press, Fig. 2 shows a iront view oi' Fig. l, Fig. 3 shows a plan-view on line A-B oi Fig. l.

The lower plate l) is iirmly mounted in an iron i'rame a. Above the plate b I arrange a movable plate c which is connected to a spindle d by means of which the plate c can be moved up and down in a well known manner. The connection between the movable plate c and spindle 0l is made by two supports e carrying on the lower flange a number e. g. eight i'lat springsfl-fs. rEhe plate c is supported by two spindles gl-g2 which are mounted in flat rails gl-gz forming bearings 'for said s indles and placed across the supports e. lly means oi' said spindles g1 g2 the plate c can be suitably7 drawn toward the supports e and the springs 1--f8- By this motion the springs are caused to rest against supports itl-hs mounted upon the upper late c to which they transfer their elasticity. It' a smaller wooden plate is to be veneered the saine is laid upon the center ci the lower press plate b. In this case it is superfluous to engage the outer pairs of springs ff2 f7f8.

Specification of Letters Patent.

Application filed October 15, 1908.

Patented May 1 l, 1909.

Serial No. 457,873.

It is i'or this reason that I arrange next to each oi' the inner four supports 7a3-71 a ilat rail iS-fi which are connected by two rails k1 and These rails are mounted in crossgrooves of the supports 7b3-#L6 and connected by a flat rail m. Connected to the rail fm. is an arm m1 guided in a groove oi' the support hES and pivotally connected to a lever o pivotally fastened by the pivot y) to the support LS. By moving inward the lever 0 the slide formed by the parts iS-te, k1, k2, m, m1 is pushed so i'ar inside that the rails fia-t6 come to rest upon the supports 7a3-h6. rl`he plate c is now moved toward the spindles ,-92 whereby the springs fB-f 6 are at once engaged while the pairs oi the outer springs f1 f2 f7 f8 only approach their respective supports h, h2 7L, its and are disengaged by the inward motion oi' said lever 0.

The single i'eatures oi my device can oiI course be changed within the limit oi' my invention.

W'hat I claim as new and desire to secure by a United States Letters Patent, is

In a veneering press the combination oi' a movable press plate (c) acting under the ini'luence oi springs, a movable slide consisting of two rails (Irl and k2) of a cross bar (m) oi an arm (m1), a pivotally mounted lever (o) connecting to said slide, four cross-bars (i3-i6) mounted across said slide, and adapted to 1engage the `four inner pairs oi' springs (f3-f6) and to disengage the two outer pairs of springs (f1 f2 f7 j@ if the said lever is moved inward, substantially as described and ior the purpose set forth.

In testimony whereoiI I have hereunto signed my name this 29th day oi July 1908, in the presence oi two subscribing witnesses.
